Profits at Nigella Lawson's production company, which makes her TV cookery shows and runs her successful website, increased more than 20% last year to £2.85m.

Lawson's company Pabulum Productions had shareholders' funds of £2.85m, according to a snapshot report as at 31 August last year published by Companies House on Thursday.

This included cash "at bank and in hand" of £2.56m.

The company, which was co-founded in 2001 with business partner William Miller, makes shows such as BBC2's Nigella's Kitchen and houses her nigella.com website.

The money made by her firm represents just a fraction of Lawson's annual income as it does not include earnings from hugely lucrative enterprises such as the sales of Lawson's cook books.

She has sold more than 3 million books worldwide.

It also exlcudes earnings from Lawson's Living Kitchen cookware range, which is sold in stores including John Lewis.

Lawson recently appeared as a mentor on Channel 4's The Taste, which she originally worked on in the US

Pabulum Productions has also made TV shows including Nigella Express for the BBC, and the Channel 4 series Forever Summer With Nigella.

Lawson's personal fortune is estimated to be worth more than £15m.
